Great colors, small flaw

Very beautiful colors!
Unfortunately, the white chalk runs out a little. This I noticed already when unpacking. But there is only minimal and does not affect the writing ansich.
We use them on a self-adhesive magnetic board film in our kitchen for notes / appointments / shopping lists. If the notes remain longer it gets you no longer chalk residue away. While it does not provide for correct color more, but somehow it has "burned". However, not sooooo bad for me. You only see at closer inspection.
